Dock causing screen to go dark. Help.

Dock for Moto Droid worked as advertised for a few hrs, then would go "dark" and touch buttons were flashing. Only thing that would stop the flashing was to press the power button. (but screen went blank again after hitting the return button)

I think the root cause of the problem was the screen BRIGHTNESS setting. I had downloaded a widget that would enable manual adjustment of the brightness setting. I believe the lowest brightness settings are too low for the Docking Station display to be visible in any light. When the brightness was reset to the "Automatic" setting using the Android default "settings" interface, the issues were (apparently) resolved.
